Core Viewpoint - The article highlights the significance of rare earth elements, which are crucial for manufacturing, and emphasizes China's efforts in exploring and securing these resources in remote mountainous areas [1][3]. Group 1: Industry Overview - Rare earth elements are defined as a group of 17 chemical elements in the periodic table, not merely as soil [1]. - China is recognized for its rich deposits of rare earth elements, particularly in its southwestern mountainous regions [1]. Group 2: Exploration Efforts - Geological teams employ traditional methods, such as "Gannan drilling," to extract soil samples from depths of up to 20 meters for testing [1]. - Each exploration area is meticulously divided into hundreds of grids, with drilling conducted in each section to obtain precise data [3]. - The successful identification of exceptionally rich medium and heavy rare earth mineral deposits is noted as a significant achievement for safeguarding national manufacturing capabilities [3].
